Statless Session Bean FIFO Behaviour

Question

Hi,
I'm using WL81, and would like to ask if its possible to enforce FIFO behaviour for session bean pools? - that is, given the situation of only 1 initial bean and max bean count is 1 for the bean pool, the request for the beans would be served according to there arrival time's chronological order.
regards,
GB

Hi,
here is the sample example for stateless bean which for j2ee server..
home.java
import java.rmi.*;
import javax.ejb.*;
public interface home extends EJBHome
     public remote create() throws RemoteException,CreateException;
remote.java
import javax.ejb.*;
import java.rmi.*;
public interface remote extends EJBObject
     public String display() throws RemoteException;
Server.java
import java.rmi.*;
import javax.ejb.*;
public class server implements SessionBean
     public server(){}
     public void ejbCreate(){}
     public void ejbRemove(){}
     public void ejbActivate(){}
     public void ejbPassivate(){}
     public void setSessionContext(SessionContext c)
     public String display() throws RemoteException
          return "welcome";
client.java
import java.rmi.*;
import java.io.*;
import javax.ejb.*;
import javax.rmi.*;
import javax.naming.*;
public class client
     public static void main(String a[])
          try
               Context initial =new InitialContext();
               Object obj =initial.lookup("sampleserver");
          home h=(home)PortableRemoteObject.narrow(obj,home.class);
               remote r= h.create();
               System.out.println(r.display());
     }catch(Exception e)
          throw new Error(e.toString());
};//compile and create a jar, for ex "firstClient.jar"
//run in console mode
// java -Dorg.omg.CORBA.ORBInitialHost=localhost -classpath "%classpath%;firstClient.jar" client
